Re: Displayname check
<?php

function check_display_name ( $user_id ) {

}
add_action ( 'before_profile_edited', 'check_display_name' );
?>You also need in your theme’s profile.php, before the line <?php elseif ( $user_id == bb_get_current_user_info( ‘id’ ) ) : ?>
<?php elseif ( $_GET['nameclash'] ) : ?>
<div class="notice error">
<p><?php printf(__('Display name already taken by %s'), $_GET['nameclash' ]); ?>. <a href="<?php profile_tab_link( $user_id, 'edit' ); ?>"><?php _e('Edit again ยป'); ?></a></p>
</div>Also, I just set my display name to a SQL query string, yay
